[Solved] Johnny python3.10: HTTP 500 internal server error occurs

[karplus]

 

Hello, i tried to run a simple test.py as stated on this tutorial https://wiki.helionet.org/tutorials/python and this topic too:

Still i get http 500 error when i open https://karplus.helioho.st/cgi-bin/test.py ; I already checked line endings and they are in unix style; plus i wrote the code by hand directly in online text editor, and also tried copy&paste, but got no luck! Permissions are 755 as suggested by tutorial.

In logs section I always got this error: End of script output before headers: test.py, referer: https://johnny.heliohost.org:8443/ , but I used print("Content-Type: text/html\n\n"), and all the versions of Python supported by Johnny.

Where am I wrong?

Best Regards

The cgi-bin folder needs to be 750, not 777. I changed the permissions for you and the script is working now.

Thanks, works like a charm now. It would be useful for other users to update the wiki tutorial then 😃

Hello, the same problem is back after re-enabling my Johnny account, I waited 6 hours since mail of succeeded renewal.

Permission of https://karplus.helioho.st/cgi-bin/test.py is 755 and cgi-bin folder is 750.

Python versions have changed on the new Johnny. If it was using 3.10 you probably need to update your shebang lines to use 3.12 or 3.9

#!/usr/bin/python3.12 or #!/usr/bin/python3.9

Hello, i did some tests using my scripts that were fully working before the last july johnny raid crash, and i found that these python modules are now missing:

• python3.12: pandas, bs4/beautifulsoup4, python-dateutil
• python3.9: pandas, bs4/beautifulsoup4, requests, pytz

It's possible in the longtime to restore them?

 

Thanks you!

Krydos can reinstall these for you.

Installed. You can see the list of installed modules on Johnny's Python 3.12 and their current versions at https://krydos2.heliohost.org/pyinfo/info3.12.py

Hello, thanks for everything, I confirm that all required modules get correctly imported now.

 

Now have one last standing error, I report this to you only as a "warning", not a requirement.In the previous johnny installation i used this line of code:

locale.setlocale(category=locale.LC_ALL,locale='it_IT.utf8')

But now it returns this error: File "/usr/lib64/python3.9/locale.py", line 610, in setlocale return _setlocale(category, locale) locale.Error: unsupported locale setting

Maybe underlying operating system is involved.

AlmaLinux 9 doesn't come with Italian installed by default. Try the code now that it's been installed.

Problem solved.

 

Thanks you!
